Description
~ S~
:
~ The invention relates tc a supporting frame for a sliding gate ; valve fox the outlet of vessels containing molten metal, and to gate valves incorporating such frames.
DE-SO 27 27 742 discloses an ad~ustable wedge shaped member, which acts through a pressure piece which is shaped to the shape of the sliding plate, provided for clamping the wearing parts or refractory plates, partic-; ularly a bottom or fixed plate or a sliding plate, in the corresponding sup-porting frame.
It is an ob~ect of the present invention to provide a clamping device for a closure plate which is of a simpler design, easier to manufac~
ture and which is releasable.
According to the present invention a supporting frame for a refractory eomponent of a gate valve for the outlet of a vessel adapted to contain molten metal has support surfaces for the refractory component and at least one eccentric mounted on the supporting frame so as to be actuatable to engage the refractory component when it is positioned in the frame in engage-ment with the support surfaces thereof and thus clamp the re~ractory com-ponent in the frame and actuatable to disengage the refractory component whereby it is no longer elamped and can be removed from the frame.
0 In a pre~erred form of the invention the supporting frame is adapted to support a refractory plate, each eccentric being mounted in the frame for rotation around an axis passing through the plane of the plate and eaeh eeeentric being arranged to engage an edge of the plate or a casing for ";~ .
the plate. ~he eccentrics provided according to the invention enable quicker clamping and releasing of the wearing parts in their supporting frame and i,, .
, aecess for operating the eccentrics is easier.
.~
~ In one speciric form of the invention the supporting frame is .
arranged to accommocLate a plate whichis elongated and two eccent,rics are :
.~i, ' ~
~4 .
~3S5~3~
; provided and are arranged symmetrically with respect to the ver-tical central longitudinal plane E of the frame at one end of the frame. This arrangement enables one to produce symmetrical clamping forces along and across the clo-.:
sure plate and so relative movement of the plate within the supporting frame during opera-tion of the gate valve is reliably prevented for all directions in the plane of sliding.
In another specific form of the invention the supporting frame is also arranged to accommodate a plate which is elongated and one eccentric is provided and is arranged asymmetrically with respect to the vertical central - 10 longitudinal plane of the frame at one end of the frame.
Each eccentric preferably has a disc shaped eccentric component which carries an eccentric face and is rotatably supported by means of at least one stub shaft on the supporting frame.
Each eccentric may be held e.g. releasably on the supporting frame by means of a lid.
There may be two stub shafts to each ecrentric~ each stub sha~t being disposed at right angles to the plane of the frame, the first stub ` shaft of each eccentric being supported in a recess in -the supporting frame.
The lid may surround the second stub shaft and support the eccen-` 20 tric.
At least one of the stub shafts preferably has a head shaped for , engagement by a tool whereby the eccentric can be rotated.
In a preferred arrangement the eccentric has a central hole shaped f for engagement by a tool whereby the eccentric can be rotated. This means that the overall height of the eccentric can be smaller, or for equal heights the bearing surface of the stub shafts can be increased.
, It is also preferred that the eccentric face has a self locking ,' pitch which means that a special locking dev ce for the eccentrics in the ~-, 3~
,` clamping position is not needed.
'~he invention also extends to the com~inatlon of the supporting frame and a refractory plate at least partially surrounded by a metallic casing on which each eccentric acts.
~ The present invention ma~ be put into practice in various ways and ,~ three specific embodiments will be descri'bed by way of example with reference to the accompanying drawings in which:
Figure 1 is a view from below of a Pixed plate mounted in accor-dance with the present invention in a supporting f'rame and 'housing;
Figure 2 i8 a longitudinal cross-section along the line II-II in Figure l;
Figure 3 i8 a transverse cross-section along the line III-III in " Figures 1 and 2;
Figures 4a and 4b are an elevation and a plan respectively of an alternative embodiment of an eccentric for use in accordance Nith the present invention; and Figure 5 is a diagrammatic plan VieN of a third embodiment showing a single eccentric mounted on the supporting frame of a central sliding plate '~ for a three-plate gate valve.
Figures 1 to 3 illustrate the invention ~orclamping wearing parts , of a gate valve for the outlet Or vessesl containing molten metal, using a ,j stationary bottom plate 1 which has symmetrically rounded narrow ends and a metallic casing 2 which for example may be a dead mould enclosing cast refrac-A tory concrete. For simple replacement the bottom plate 1 is clamped in a supporting frame 3 bythe metallic casing 2, which is filled with refractory material and at leas-t partially encloses the refractory material. The sup-porting frame 3 is attached by screws 13 to a housing 12 for the gate valve so that it can be easily released. Two eccentrics or cams 4, ~hich can 3S~
rotate around vertical axes are arranged in the supportin~ Prame 3 in posi-tions sy~etrical with respect to the vertical longituainal central plane E
of the bottom plate 1. Each of the eccentrics has an eccentric face 5 with self locking pitch 20 including a ramp portion 21 provided on a disc shaped eccentric component 6. Each of the eccentrics acts with its eccentric face 5 on the outer surface of the metallic casing 2 exerting clamping forces on -~
the bottom plate 1 in the longitudinal di:rection ~the operating direction of the gate valve) as well as in the transverse direction. Stub sharts 7 and o extend upwards and downwards from the disc shaped eccentric or cam component 6 i.e. at right angles to the plane of the plate. The upper stub shaft 7 is rotatably mounted in a recess 10 of the supporting frame whilst the head 11 of' the stub shaft 8, pointing downwards, extends through the opening in a part circular lid 9. The lid 9 is attached to the supporting frame by means of screws 14 in such a way that it supports the corresponding eccentric 4 at . 1 . the eccentric component 6. The head 11 has, as an example, a s~uare or , cruciform head adapted for en6agement of a tool for turning the eccentric.
The other end of the stub shaft 7 may be similarly provided with a square or cruciform head and then access can be had to the eccentrics for operation of ~ the eccentrics from whichever side of the frame is free at the time.
; 20 Figures 4a and 4b illustrate an eccentric 4 according to the inven-tion, in elevation and in plan respectively, with a central eccentric com-ponent 6 which has an eccentric face 5 with a self locking pitch 20 on its circumference and a ramp 21 and stub shafts 7 and 8 sticking out from the eccentric component 6 on both sides. Instead of a disc with a spiral sbaped boundary surface 20 according to Figure 4b, the eccentric element 6 can also i be provided as a circular disc which is positioned eccentrically with respect to the stub shafts 7 and 8. In Figure 4b a shaped hole 16, here illustrated by a square hole, for engagement by a turning tool passes through the eccen-_ 4 _ 3~
tric 4. Here all o~ the outer sllr~aces o~ the stub shafts 7 and ~ are avail-able as bearing surfaces.
Figure 5 shows an arrangement o~ a single eccentric 4, wbich may be shaped as in Figure l or Figure 4b, acting on one of the narro~ ~iides~ which is rounded in the usual way, of a central plate (not sho~m) and generating the required clamping forces in the longitudinal a6 well as in the transverse direction. The supporting frame 15 is intended for the sliding central plate of a three plate gate valve. The eccentric 1, is shown positioned asym-metrically with respect to the vertical longitudinal central plane E. The invention can also be applied to the clamping Or a refractory plate in the lowest stationar~ frame of a three plate gate valve or in the sliding plate-frame of a two-plate gate valve, using the arrangements shown in Figures l to 3 or l to 3 and 4a and 4b or Figure 5.
